Nail clipper

Abstract

Disclosed is a nail clipper provided with cutting edges having a curvature corresponding to a section and a curve of a nail, in which a blade body can be replaced with one having suitable cutting edges according to a shape and a size of a nail. In a nail clipper according to one embodiment of the present invention, cutting edges formed at one ends of upper and lower blades of a blade body are curved with a first curvature to the one end of the blade body while being bent with a second curvature with respect to the blade body. In a nail clipper according to another embodiment of the present invention, a blade body is removably received in a casing and a lever for applying force to the blade body is coupled to the casing. Since the blade body can be removably disposed in the casing, thus, it is possible that one having cutting edges corresponding to a size of the nail can be coupled to the casing, instead of the blade body.

         1 . A nail clipper comprising: 
 a blade body including an upper blade having a cutting edge at an end thereof and a lower blade having a cutting edge at an end thereof, of which the other end is joined to the other end of the upper blade, the cutting edges, which are provided at one ends of the upper blade and the lower blade of the blade body, being bent toward the blade body with a first certain curvature while being curved with reference to the blade body with a second certain curvature; and    a lever assembly which is associated with the blade body at a position adjacent to one end of the blade body, for applying force to the one end of the blade body so that the cutting edge of the upper blade is engaged with that of the lower blade.    
     
     
         2 . The nail clipper as claimed in  claim 1 , wherein the first curvature of the cutting edges which are respectively provided at the one end of the upper and lower blades, corresponds to that of a nail end.  
     
     
         3 . The nail clipper as claimed in  claim 1 , wherein the second curvature of the cutting edges which are respectively provided at the one end of the upper and lower blades, corresponds to a sectional curvature of a nail end.  
     
     
         4 . A nail clipper comprising: 
 a blade body including an upper blade having a cutting edge at one end thereof and a lower blade having a cutting edge at one end thereof, of which the other end is joined to the other end of the upper blade;    a casing for releasably receiving the blade body; and    a lever which is combined with the casing adjacent to the one end of the blade body received in the casing, for applying force to the one end of the blade body so that the cutting edges of the upper and lower blades of the blade body are engaged with each other.    
     
     
         5 . The nail clipper as claimed in  claim 4 , wherein the blade body has an aperture at the other end thereof.  
     
     
         6 . The nail clipper as claimed in  claim 5 , wherein the lever includes a body, a bent portion which is bent at a desired angle with regard to the body, and a pair of protrusions respectively extending at a desired length from both sides of the bent portion.  
     
     
         7 . The nail clipper as claimed in  claim 6 , wherein the casing includes a bottom wall and a pair of sidewalls extending upwardly from both sides of the bottom wall, the sidewalls respectively having thru-holes adjacent to the one end thereof, the thru-holes having a desired diameter, which are opposite to each other.  
     
     
         8 . The nail clipper as claimed in  claim 7 , wherein the casing has a cover at the other end thereof in order to protect the blade body and the lever, the cover being pivotally installed to the casing with respect to the casing.  
     
     
         9 . The nail clipper as claimed in  claim 8 , wherein the sidewalls of the casing respectively have a recess in order to receive the protrusions extending from the sidewalls of the cover so as to fix the cover to the casing.  
     
     
         10 . The nail clipper as claimed in  claim 7  or  8 , wherein the lever is combined with the casing in such a manner that the protrusions respectively extending from the sidewalls of the bent portion are inserted into the thru-holes respectively formed at the one end of the casing.  
     
     
         11 . The nail clipper as claimed in  claim 6 , wherein a pair of protrusions extends at a desired distance from each other from a front end of the bent portion of the lever, in order to remove the blade body from the casing.  
     
     
         12 . The nail clipper as claimed in  claim 11 , wherein the upper blade of the blade body has a pair of rectangular grooves on an upper surface thereof in order to receive the protrusions provided at a front end of the bent portion of the lever.  
     
     
         13 . The nail clipper as claimed in  claim 12 , wherein the rectangular grooves which are formed on the upper surface of the upper blade of the blade body, are divided by a plurality of partitions having a slanted surface declined toward the cutting edge.  
     
     
         14 . The nail clipper as claimed in  claim 6 , wherein the casing has a bottom wall, two sidewalls extending upwardly from both edges of the bottom wall and a rear wall extending upwardly from a rear edge of the bottom wall and being connected to the sidewalls, the sidewalls respectively having a rectangular thru-hole at the one ends thereof to receive the protrusions formed at both sides of the bent portion of the lever respectively.  
     
     
         15 . The nail clipper as claimed in  claim 14 , wherein the casing has a fixing projection at a desired portion of the bottom wall, which is inserted in the thru-hole formed at the other end of the blade body so as to fix the blade body to the casing.  
     
     
         16 . The nail clipper as claimed in  claim 15 , wherein the lever coupled to the casing is able to slidably and reciprocally move along the rectangular thru-hole formed in each sidewall of the casing.  
     
     
         17 . A nail clipper comprising: 
 a blade body including an upper blade having a cutting edge at one end thereof and a lower blade having a cutting edge at one end thereof, of which the other end is joined to the other end of the upper blade; and    a casing which receives the blade body, for applying force to the one end of the blade body so that the cutting edges of the upper and lower blades of the blade body bring into contact with each other.    
     
     
         18 . The nail clipper as claimed in  claim 17 , wherein the casing includes a bottom wall, sidewalls extending upwardly from both sides of the bottom wall, a rear wall extending upwardly from a rear end of the bottom wall to be connected with the sidewalls and a traverse member extending between one ends of the sidewalls to fix the blade body to the casing.  
     
     
         19 . The nail clipper as claimed in  claim 18 , wherein the sidewalls of the casing respectively have a rectangular shaped thru-hole at a lower portion thereof.  
     
     
         20 . The nail clipper as claimed in  claim 19 , wherein the casing includes a lever disposed under the blade body to be able to slidably and reciprocally move along the rectangular thru-hole, the lever applying force to the one end of the blade body so that the cutting edges of the upper and lower blade of the blade body bring in contact with each other.  
     
     
         21 . The nail clipper as claimed in  claim 20 , wherein the lever includes a body having a slanted surface and protrusions extending from each side of the body to be inserted into the rectangular thru-hole formed in the sidewalls of the casing.
